It is surprising how little has changed, though. We still face many of the same problems builders in the 1930s and '40s faced: material scarcity, high peaks of activity followed by deep troughs of low demand, labor shortages, government intervention, consumer confidence, adoption of new technology, changing building practices and lifestyle trends. The issues the editors addressed in those first years are the same things we speak of today.

When Professional Builder editors began looking back over our history, we noticed each 10-year period seemed to have its own themes, a zeitgeist of the decade. In our 70-year history series of articles, we've identified those major movements, report on what's happened in housing over the last 70 years, examined how PB reported on the industry, and recognized the events that have shaped where we are today.
